Question

What general trends characterized the evolution of Homo cranial morphology?

a) increasing cranial capacity and more oval-shaped crania through time
b) decreasing cranial capacity and more oval-shaped crania through time
c) increasing cranial capacity and more rounded crania though time
d) decreasing cranial capacity and more rounded crania through time

Answer 1

The correct answer is option - C.

Explanation:

Homo cranial morphology is the size and shape of the skull of the humans and the evolution of cranial morphology has followed the general trend in which the shape of crania has become more rounded over the period of time of evolution.

The cranial capacity of hominids is increased in the course of the evolution as the size of the brain is triple in the past seven million years. The skull is over all changed during evolution for example, the large canines were no longer needed for tearing and eating the food.

Thus, the correct answer is option - C.
